高、低帮篮球鞋对落地时踝关节稳定及肌肉功能影响的研究

    Effects of High-top and Low-top Basketball Shoes on Ankle Stability and Muscle Function during Landing

    • 摘要: 目的:探讨高、低帮篮球鞋对落地时踝关节内翻的运动学、地面反作用力及下肢主要肌群活动的影响, 尝试理解高、低帮篮球鞋与踝关节落地稳定之间的关系;方法:13名受试者分别穿着高、低帮篮球鞋, 手抓杠悬于空中, 从40 cm高度分别垂直下落至内翻15°、内翻30°、内翻25°伴随跖屈10° (25°+10°) 、内翻25°伴随跖屈20° (25°+20°) 的倾斜面上, 分析其踝关节运动学、地面反作用力及小腿主要外翻和背屈肌群 (胫骨前肌、腓骨长肌和腓骨短肌) 的肌电活动;结果:高、低帮鞋对内翻角度的变化、最大内翻角速度和地面垂直及水平冲击力没有显著影响;在15°倾斜面时, 穿着高帮鞋出现预激活时间比低帮鞋晚 (P<0.05) , 同时, 在15°和25°+20°下腓骨长肌和腓骨短肌落地前50 ms的平均振幅更小 (P<0.05) ;结论:选取的高帮鞋对踝关节的运动学和冲击力的改变不显著, 但却在一定程度上影响了周围肌肉的预激活, 对限制踝关节活动起到了积极的作用。

       

      Abstract: Purpose:To evaluate the effect of high-top and low-top basketball shoes on ankle inversion kinematics, ground reaction forces and relevant muscle activities, as well as the relationship between shoes and ankle stability during landing.Methods:13 subjects were required to wear high-top and low-top basketball shoes to land on an inversion & plantarflexion tilting platform.Kinematics, ground reaction force and corresponding muscles activities of ankle were collected and analyzed.Result:No significant effect was found in inversion angle, maximum inversion angle velocity, and ground reaction force for vertical & horizontal directions.However, high-top shoe showed a later onset of pre-activation than low-top shoe in four tilting conditions, especially at a 15° inversion condition (P<0.05) ;meanwhile, the amplitude of pre-activation of peroneus longus and peroneus brevis for high-top shoe were smaller than low-top shoe at 15° inversion condition and 25° inversion plus 20° plantarflexion condition, respectively (P<0.05) .Conclusions:The high-top shoe selected in this study has little effects on ankle kinematics and ground reaction force, but has certain positive effects on ankle muscle pre-activation and limitation of range of motion.
